I'm not really that picky, but I was just curious as to why u advertise for 360? Does the 10mb go to some other process like xen? |

The kernel itself occupies some of that RAM, just like on a physical machine.
cat /proc/meminfo, and you'll see how it's broken out.

I do get see all 360 in 'free -m', running Ubuntu 7.10 and "latest 2.6 series" kernel.
Check that you gave that Linode your full memory allotment in the configuration profile - if you didn't choose 'Max' and instead chose to limit it, then accidentally typed 350 instead of 360. |

This could also be Xen vs UML
UML:
# free -m
total used free shared buffers cached
Mem: 347 194 153 0 68 85
-/+ buffers/cache: 40 307
Swap: 255 19 236
-------------------------------------------------------------------------------
Xen:
# free -m
total used free shared buffers cached
Mem: 360 340 20 0 80 151
-/+ buffers/cache: 108 251
Swap: 255 3 252 |

This way shows ~358mb, which is by far close enough for me. I forgot about /proc. Still in the learning curve for linux myself. |

I switched kernels, was running 2.6.24-linode8 but now I am using 2.6.18-domU-linode7 because of a time sync issue.
Anyway, check this out.

I think that means this is very independent answer depending on plenty of variables. |
